ID and IDREF

[geoff]

Hello,

Why does this not work:

<billTo id="addr-1">
<company>The Skateboard Warehouse</company>
<street>One Warehouse Park</street>
<street>Building 17</street>
<city>Boston</city>
<state>MA</state>
<postalCode>01775</postalCode>
</billTo>

<shipTo href="addr-1"/>

.. . . billTo and shipTo are defined as the same in the schema and I included
the following in the schema definition:

<xsd:attribute name="id" type="xsd:ID"/>
<xsd:attribute name="href" type="xsd:IDREF"/>

.. . . however, xml notepad says, 'the element shipTo has incomplete
contents'. If I populate shipTo with the same info as billTo, it works fine
but the referencing of billTo does not seem to work or is it a limitation of
xml notepad?

Thanks.

If the schema for shipTo defines child elements then you have to include
those child elements literally. There is no way to include them using a
link mechanism, that is not how XSD schemas work.
All ID/IDREF allow you is to refer to other components for instance
<address id="addr1">
<company>The Skateboard Warehouse</company>
<street>One Warehouse Park</street>
<street>Building 17</street>
<city>Boston</city>
<state>MA</state>
<postalCode>01775</postalCode>
</address>

<billTo href="addr1"/>
<shipTo href="addr1"/>
but then the schema would not define child elements for billTo and
shipTo, it would just define the attribute and its type.

After I uploaded that, I can see it has some problems, oh well.
